MACHINE FOR MANUFACTURING ROOFING-TILES.

SPECIFICATION forming part of Letters Patent N0. 597,447', dated January 18, 1898.

Application led May 8, 1896. Serial No. 590,752. (No model.)

To @ZZ whom it may conceiva- Be it known that I, ABRAHAM WEIL, merchant, of Steinheim', "Westphalia, in the Kingdom of Prussia, German Empire, have invented new, and useful Improvements in Machinery for the Manufacture of Rooiing-Tiles, of which the following is a speciiication.

This invention relates to machinery for the manufacture of rooiing-tiles having upper and lower overlapping fillets.

In the accompanying two sheets of drawings, Figure 1 is a longitudinal section of the upper part of a machine constructed in accordance with my invention for the purpose 'of forming the ripper overlapping fillets on the green or unbaked body of the roofing-tile. Figs. 2 to 7 show another arrangement of the machinery for the same purpose, Fig. 2 being a vertical section, Fig. 3 a plan, and Figs. 4 to 7 separate views of parts of the same inachine. Figs. 8 to 10 show the moldingplate and mold-lining for forming the lower overlapping fillets, which are provided with a projecting tongue, Fig. 9 being a section taken on line z cf of Fig. S.

Referring to Fig. 1, it will be seen that the mold 7, with the mold-plate belonging thereto for the formation of the under side of the roofing-tile, is contained within the mold-frame 6, and that the main body of the unbaked roofingtile 8 is carried by this moldplate. The hopper 9 is connected with the bridge 10, on which is pivoted a bell-crank lever 1l. Be-

- low the bridge 10 is arranged the plate l2,

which rests on the tile 8 and is used in the formation of the upper overlapping fillets. It is provided with guide-screws 13, which move in the guide-slots 14 of the bridge 10. The plate 12 is connected with the bell-crank lever 11 by means of a pin 15. 1When the bellcrank lever 11 is .moved in the direction of the arrow 16, the plate 12 is moved in the direction of the arrow 17, so that the tile, with its overlapping fillets 3, is free to be pushed out by any suitable means.

In Fig. l the apparatus for the production of the recesses in the lower overlapping fillets is omitted for the salie of clearness, because the figure only relates to the upper part of the machine. In the arrangement of the ma` chine shown in Figs. 2 and 3 the apparatus of the slides 23 terminates in a horizontal ,I plate 24, on which is fixed the bridge 25, by

means of which the two slides 23 are connected together. IFach slide 23 is also provided with a downwardly-projecting arm 26. To each bracket 2l is pivoted a two-armed lever 27, which is coupled by the connectingrod 28 with the arm 26 of each slide'. On the plates 24 of the slides 23 is mounted movably the hopper 29, with its slidebars 30 guided by the slots 3l and guide-bolts 32. The hopper 29 can consequently be moved to a certain extent to and from the bridge 25, notwithstanding that both parts remain connected with the slides This movement is eected by means of the following arrangements: Each slide-bar 30 is furnished with an arm 33, which is connected with the lever 34. This lever 34 is also connected with the bridge 25 by means of the link 35. wWhen the lever 34 is moved into the position shown in Fig. 2, the hopper is moved toward the bridge 25, and

when the lever 34 is moved in the opposite di-4 rection the hopper is moved a short distance away from the bridge. In the bridge 25 are guided the two plates 37 and 38 for the prod uction of the tooth-like projections or notched grooves in the upper overlapping fillets of the tile. The upper plate 3S is provided with a bolt 39, which takesinto and is movable vertically in the box or socket 33, formed on the bridge 25. This bolt is slotted at its lower part, as shown in Figs. 4 to 7. The box yor socket 36 is split in front, as shown in Figs. 2, 3, 4, and 7, and can be 'closed onto the bolt 39 by means of the screw 40. It is provided at its lower part with two lugs 41, in which is pivoted the forked lever 42 by means of the fulcrum-pin 43. On this bolt is Xed an eecentric 44, which takes into the slot in the bolt 39 and is provided with a pin or projection 45, which takes into the slot 47 in the plate 37. 4In the bolt 39 are also two slots 46, which enable it to move vertically in the box or socket 36, notwithstanding that the bolt 43 IOC) ' passes through it. The lower plate 37 is provided with a guide-piece 46X, which is guided in the slot 48 of the plate 38.

The action of the machine is as follows: The tile is delivered into the machine on the mold-plate in the usual manner. slides 23 and the bridge 25 are then brought into the position shown in Fig. 2 by moving the lever 27 in the direction of the arrow 49. When this is done, the lever 34 is moved into the position shown in Fig. 2, so that the hopper 29 takes the position shown in Figs. 2 and 3. rIhe lever 42 is then moved downward, so that the plates 37 and 3S take the position shown in Fig. 2. The material to form the overlapping iillets is then placed in the hopper 29 and is rammed down tightly. When this is done, the superiiuous material is cut off by means of the knife l, operated by the lever 50, and the lever 34 is moved so as to move the hopper 29 outward to the extent of the width of the overlapping fillets, the plates 37 and 38 still supporting the projections of the upper overlapping fillets. Vhen the hopper 29 has thus been removed,the lever 42 is moved upward. The pin 45 of the eccentric 44 bea-rs against the guide-piece 46 and moves the lower plate 37 toward the right until the pin 45 passes beyond the guide-piece 46X. At that moment the eccentric 44 comes into action and presses against the part 52 of the bolt 39, Fig. 4, so that the two plates 37 and 38,which are connected together by means of guide-screws, are raised up with the bolt 39 until they stand higher than the upper edges of the upper overlapping iillets. The lever 27 is then moved in the direction of the arrow 53, (see Fig. 2,) whereby both the hopper and the bridge are moved to the left. The tile thus finished can then be pushed out out of the machine in the usual way.

The mold-plate for the formation of the under side of the tile- (see Fig. 8) is used in the manufacture of such roofing-tiles as have their lower overlapping Iillets provided at the angle where they come together with short projections which have angular tongues that take into the groove of the upper overlapping fillets. In order to bring the base of the recess required for the production of the pro! j ectin g tongue in the lower overlapping fillets even with the under side of the tile, the moldfV plate l is-furnished, at the point on the lower side at which the slide for the production of the recess in the lower overlapping fillets is situated, with a hollow impress 2, which receives the slide. 'By this means the lower surface ofthe hollow impress 2 is brought to the same level as `the upper surface of the mold-plate, asshown in Fig. 9. The vertical wall 3 of the mold-plate extends a little back for thelength of the hollow impress 2 in order to make the overlapping fillet broader and to form the recess therein by means of the slide pressed in through the aperture 3X, provided for that purpose. Furthermore, the mold-plate is shaped at the truncated corners The two 4 and 4 to fit into the mold-lining 5. (See Fig. l0.) The object of thesetruncated corners is to furnish the roofing-tile with angular offset jointing edges.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a machine for forming the overlapping fillets on rooiing-tiles the combination of the frame 6, with the mold 7 having the moldplate for the formation of the under side of the roofing-tile, the hopper 9, the bridge l0 connected with the hopper 9, the bell-crank lever l1 pivoted on the bridge lO, and the plate l2 used in the formation of the upper overlapping llets and connected with the bell-crank lever ll, substantially as and for the purpose set forth. f

2. In a machine for forming the overlappin g filletsA on roofin g-tiles, the combination of the bridge 25, with' the two plates 37 and 3S connected together movably with reference to one another, by means of screws, the plate 38 being provided with a slotted bolt which is movable vertically in a box or socket 36 connected with the bridge 25, an eccentric 44 operated by a lever 42 pivoted to the boX or socket 36, and a pin or projection 45 iiXed to the eccentric 44 and taking into a slot 47 in the plate 37, combined, arranged and operating so as to produce irstly a movement of the lower plate 37 toward the right, and secondly i an elevation of both plates together, substantially as described.

bridge 25, with the two slides 23 rigidly connected with the bridge 25, the hopper 29 mounted on the slides 23, and a two-armed lever 27 coupled by a connecting-rod with each slide 23, substantially as and for the purpose set forth.
